NEWPORT BEACH, Calif. – August 3, 2006 – The TriZetto Group Inc. (NASDAQ: TZIX) today announced the release of its CareAdvance Enterprise™ Version 4.1 software, which allows health plans to automate utilization, case, disease and population management, and to extend a personal health record (PHR) and personal health management tools to their members. Continuing its leadership role in consumer-focused care management, TriZetto has enhanced the system with important new functionality to further streamline and improve medical management. For the first time, providers can access CareAdvance Enterprise to conduct administrative and clinical functions via a portal on the health plan's website. The system also includes new member incentive programs that extend beyond traditional disease management, as well as embedded clinical content to improve utilization management by automatically determining standard guidelines for care.

"TriZetto is committed to helping health plans partner with consumers to shape behavior that can lower health costs and improve outcomes," said Robert London, M.D., chief clinical officer and head of the Cost and Quality of Care unit for TriZetto. "We've extended CareAdvance Enterprise to enable greater provider involvement in care management, and within our personal health record we've also included member self-management programs that health plans can use to reward healthy behaviors. TriZetto's goal is to provide the customized information and tools necessary for better communication among member, plan, and provider, each a crucial link in effective care management."

New Provider Interface

CareAdvance Enterprise's new provider interface and tools tightly integrate physicians, hospitals and other providers into the care process, to help ensure maximum efficiency and quality care. A specially designed portal allows providers to log-on to the health plan's website and link to the CareAdvance Enterprise system to conduct administrative and clinical functions online. Providers can submit and track authorizations; access key patient information, such as current prescriptions and health conditions; initiate a care plan or assessment; send and receive messages; view member alerts; and enter progress notes.

New Consumer Self-Management Programs

The latest version of the population and personal health management module of CareAdvance Enterprise, called Personal CareAdvance, also includes new self-management programs, which use automation to extend health guidance to a broader population of members, especially those who do not warrant nurse time over the phone. In addition to valuable PHR capabilities, the system now enables the health plan to automatically identify, educate, and manage members who could benefit from enrollment in appropriate self-management programs. The system can track members' progress through the personalized programs - including whether they have completed interactive tutorials and assessments for a wide variety of conditions, such as smoking, diabetes, or lower-back pain - and then extend incentives to those who have taken positive steps to improve their health. When various health and wellness goals are met, members become eligible to receive rewards ranging from basic gift cards, to a contribution to their health spending account or additional health plan benefits.

New Integrated Clinical Criteria for Standards of Care

To help the health plan's case managers better evaluate the medical necessity of a particular procedure, hospital admission or extended hospital stay, TriZetto has now integrated a national set of clinical criteria into the CareAdvance Enterprise workflow tool. After case managers input key information on the patient, provider, diagnosis and procedure, an automated rules engine determines the nationally accepted standards of care. Case managers can follow these guidelines when authorizing procedures, hospital admissions, and other treatments for members. The embedded clinical criteria in CareAdvance Enterprise can help eliminate guesswork by standardizing the authorization review process, resulting in more efficient utilization management.

According to Roy Schoenberg, M.D., M.P.H., senior vice president and chief internet solutions officer for TriZetto, another significant enhancement to CareAdvance Enterprise is its new data interface package, which allows plans to easily exchange information with multiple internal and external systems, such as those for claims, predictive modeling, pharmacy, home biometrics, and labs. The availability of these data sources allows the health plan to deliver a far more personalized, accurate communication and intervention to all three constituents - members, care managers and providers.

"With CareAdvance Enterprise, health plans have the scalable infrastructure they need to introduce a wide array of care management programs, using the latest and most diversified communication vehicles," said Schoenberg. "We have invested in the agility of the system, its ability to constantly rethink and adapt its behavior based on the incoming data streams.

"Our latest version incorporates clinical criteria and guidelines into workflow for case and utilization management, all driven by automated rules that yield efficiency, quality and consistency of management. The extensive automation now allows us to blur the line between traditional, phone-based medical management and electronic disease and health management for the population at large. By introducing advanced customization and configuration tools, we've opened our platform to health plans and content providers, creating a solution that can be continuously flexed to serve the plan's evolving business agenda and unique vision."

About CareAdvance Enterprise

CareAdvance Enterprise is software that automates care management along the entire continuum of health, from the moment a member joins a plan, to when they leave the plan. The system includes two modules - Personal CareAdvance and Clinical CareAdvance - which integrate with the health plan's core information systems, aggregating the member's personal claims and diagnosis history, current prescriptions, and even laboratory data, into a single data repository. Members, their providers, and care managers can securely exchange and add information - at the member's discretion - via Internet browser, phone, fax, e-mail and other communication channels. By combining this data with an automated rules engine, the application enables health plans to send personalized information to members, including health risk assessments and reminders, secure messages, and customized health reports.
